摘要
通过对2005—2009年4-10月石家庄站(53698)自动气象站与人工观测降水量进行对比分析,发现自动气象站观测降水量与人工观测降水量存在一些偏差。进一步分析得出:观测数据采集方式不同、观测时间不一致、自动气象站雨量传感器自身原因、承接降水物形态、未定期维护而造成的测量误差以及外界环境因素是导致自动气象站和人工观测降水量观测误差产生的主要原因。
The precipitation of Shijiazhuang Station （53698） from April to October in each year during 2005 and 2009, observed by the automatic observation station and artificial observations, had some difference. The deeply analysis showed that the main reasons were as follows： Different observation ways, different observation time, rain sensor of automatic observation station itself, loading precipitation patterns, measurement errors due to no regular maintenance, and external environmental factors.
